WHEEL.

Application lled April 2,

This invention relates lo .the construction ot vehicle wheels having cast metal hubs,r sheet metal discs or Webs and tirc-support' ingk rims attached to the peripheries ot' the discs, and the object o'ivthis invention isto provide a wheel oi this character in ,which the radial cross section ot' the disc shall be a reverse curve and therefore have great stillness to resist endwise or axial thrusts.

ln the accompanying drawings, Fig. l. is an axial halt section of a Wheel embodying the present invention. Fig. 2 is a sectional view ot a modified. form oit hub construction.

vSimilar reference cl'iaractcrs refer to like parts throughout the several views.

In Fig. 1 the hub l is formed with Ya.

have conical engaging surfaces to t corre-3 sponding surfaces on the clamping rin'gfl lwhich' permits lthe holes in the clamping ring' 'port the inner or central portion of the disc; Ihe disc 1s tormed'with a circular arch and Ao n the hub tangenti-ally to 'this arch. Sutside ot the arch the disc is reversely curved toward the outer face ot thev Wheel.

the metal of the disc extends from the flange 625' ,I

.lhe details pertaining to this structure and the proportions ot' the parts, however, may all be changed by rthose skilled in the art Without departing from the spirit of my invention as set forth in the following ,n. ange 2 provided with conical bearing acesclainis.

3 and t between which bolts 5 are secured in position by nuts 6. rlhc disc 7 embodies a circular arch 8 adjacent the flange 2 and two conical portions 9 and 10 adapted to engage as usual.

the conical surfaces 'and- 4 of the flange 2. The hub cap 12 has a `flange 13 which coniriscs a circular rib 14 and an inturned 'edge 15, both of which are pressed against the conical portions 9 and 10 by the nuts 16 which therefore-secure the disc to the hub.

Outside ot thev circular arch 8 the disc is ormed with a reverse curve 17 which merges into an arched ring 18 pert'oratedto receive bolts 19. The periph-ery of 'the disc contacts with the Well known removable rim 20 along a line 21, the rim being secured in position by means ot rhn clamps 22- and nuts 23. It will be noticed that the liange 2 on the hub is substantially central with the rim 20. I` prefer to orin the inner ends .ot the nuts 16 and. the seats therefor in the flange 13 conical so that the cap 12 and flange 13 can be readily centered on the hub. The rim 20 is provided with a split ring 9A:

The construction shown in Fig. 2 is somewhat similar to that shown in Fig. 1. The liangc G7 on the hub G8 has two approximately conical bearing surfaces (if) and which tit the inner side of the inner edge oi: the disc 7 2 which. held in position' by the clamping ring'73, bolts 74 and nuts 75, the bolts being secured in position by means of nuts 76. The clamping ring has lianges .77 and 78 which tit the disc and cause a rigid engagementbetween it and the hub. In this embodiment the nuts are agam shown to l claim 1. 1n a vehicle wheel, the combination of a disc, a rim attached to the outer edge thereof, and a hub secured to the centerI of the disc, said disc being torn'ied with a con nected pair oi circular arches having their crowns in opposite directions, said huh hav-- ing a flange provided with two conical bearing surfaces inclined in opposite directions and the central portion of said disc being" formed to tit said conical Jraces.

2. ln'a vehicle wheel, the cornbinationot a disc, a rim attached tothe outer edge thereof, a hub secured to the center ol the disc, said' disc bei-ng formed with a connected pair o circular arches having their crowns V in .opposite directions, said hub having a flange provided with two conical bearing surfaces inclined in opposite directions and the central portion ot said disc being formed to fit said cinical laces, a hub cap extending around the outer end oi the huh and having?r a flange at its inner endj and a bolt to secure the hub cap, the flange on the huh and the inner portion of said disc together.

3. ln a vehicle wheel, the. combination of' a disc, a riin attached `to the outer edge thereof, a hub secured `to, the center ot the disc, said disc being Vlorn'icd with a connected pair of circulaiarchesiliaving their crowns in opposite directions, said hub having a flange provided with two conical vbearing surfaces inclined in opposite directions and .the central portion of said disc being formed to tit said conical vlaces, a hub cap enclosing the outer end of the hub and terminating at ico ying conical bearing surfaces adapted to cooperate with the conical bearing suri'aces on the iange on tlie hub to secure the disc to the hub, and means for pressing the flange on the hub cap toward the iange on the hub.

lin a. Wheel, the combination of a hub having a Acircumferential ange provided with a pair of circumferential substantially conical bearing surfaces, a disk having a circular portion at its inner edge adapted to fit against the substantially conical surfaces of the flange, a retaining member having flanges adapted to fit the said circular portion of the disk, and means t0 secure the retaining member andL disc to the flange.

In a wheel, the combination of a hub having a circumferential flange provided with a pair of circumferential substantially conical bearing surfaces, a disk having a pair of circular substantially conical portions aflapted to it against the substantially conical surfaces of the flange, a retaining member having circular flanges adapted t0 bear against the said substantially conical portions of the disc, and means to secure said parts together comprising bolts and nuts thereon having tapering conical engaging surfaces adapted to contact with the walls of holes in said retaining member.
